This personal note from the year 2004, from a grandson (my first cousin) of Dr. Whitman Smith Goodwin:
Dr. Whit bought a train ticket to the end of the line (Carbonear) in 1900. Enroute he met several politicians and businessmen from St. John's (including Sir John Crosbie), who wanted him to go to St. John's. He wouldn't because his ticket was to Carbonear. He stayed there a very short time and moved to Harbour Grace the same year. At that time he was the only resident dentist in Newfoundland. He founded the Newfoundland Dental Association and the United Towns Utilities which was bought out by Nfld. Light and Power in the 1970's. Whitman LeRoy Goodwin, son of Whitman Smith Goodwin practised together with his father and as of 2004 this represents a continuous practice of dentistry by the Goodwin family in the Harbour Grace area for 104 years.

WS Goodwin married Elsie Katherine Warren 8 July 1902 in Harbour Grace. Elsie was born in Annapolis Royal, Nova Scotia 18 August 1877. Her father James had gone there to learn the carriage trade. James was married to Annie Alcock.
